Most of the changes are just adding GetDesignSettings() before every occurence of m_NetClasses.
More complex changes:
class_netclass.cpp - NETCLASS does not store the pointer to the parent BOARD anymore. Added function SetParams( BOARD_DESIGN_SETTINGS& ).
class_netclass.h - Removed GetTrackMinWidth(), GetViaMinDiameter(), GetViaMinDrill(), GetuViaMinDiameter(), GetuViaMinDrill() as they were refering to BOARD_DESIGN_SETTINGS anyway (they are not net class specific).
kicad_plugin.cpp - filters out empty nets (that are anyway not saved) when storing net class information. Previously it was done in NETCLASS::Format() function.

Moved a few one-liners of BOARD_DESIGN_SETTINGS class to the header file.

Moved menuCopy to CONTEXT_MENU copy constructor.

Cursor position is saved as a field in order to avoid drifting of items while they are being dragged and rotated/flipped.

Added WX_UNIT_TEXT - wxWidget control for inputing sizes using different units (mm, inch, internal units).

Resolved HOME hot key conflict between menu entry (Zoom Page) and event assigned to the hot key in the ACTION_MANAGER.
Conflicts:
	pcbnew/menubar_pcbframe.cpp

Added preference for selecting tracks/vias/graphics if there is a module present in the selection point.

Algorithm is still the same... now need to know what it really meant to do

*)  Implement a framework for "Data Load On Demand".

*)  Implement FP_LIB_TABLE* PROJECT::PcbFootprintLibs(), which is the first
    prototype.

This allows the project specific footprint tables to be part of the Module Editor
when invoked from Eeschema.

Fix an annoying behavior of new quasi modal frames  on Windows (when closing them, the caller frame was no more on top )

fix also a bug in python script round_value_robin.py.

*) Eeschema can now show the footprint editor.

*) Eeschema can now invoke the footprint picker from the library part field editor.

*) KIWAY_PLAYER::ShowModal() takes aResultantFocusWindow that tells what window
   to give the focus to.  Required since frames are often near the top of the
   hierarchy and they are invoked by a peer, not a parent.

Kicad: fix crash on exit, when Libedit was called during a session. It fixes also a crash if Libedit was called, closed and reopened.
Happens only if eeschema was called from the Kicad manager.

footprint editor: fix crashes. In this fix, I removed the assumption the parent frame is the board editor.
However, this assumption is still present here and there  in the moduleframe code.
